I had cooling issues in the past. I would switch to a 180 high flow stat, not a 160. I did this, along with the stewart water pump, fluidyne radiator, and the black magic (by the way, the black magic cools no better or worse than the stock fan),
You can get the high flow 180 from Sumitt or Auto Zone carries them also. I would go to auto zone because sumitt sent me the wrong one.
I had to go to an aluminum rad. I had a three core heavy duty copper/brass, and it just didnt do the job. I recommend the Fluidyne rad. Its bad a$$.
